摘要

This study performs an electrochemical experiment to quantitatively evaluate the corrosion resistance performance in a Zn-Al thermal metal spraying method and produces corrosion current density according to the type of corrosion resistance methods. In the results of the calculation, the corrosion membrane produced in a Zn-Al thermal metal spraying method showed voltage differences more than 300 mV and that demonstrated enough corrosion performance with the corrosion resistance reaction of base materials and proper Zn-Al ratio, such as 50:50. Also, the results exhibited that the corrosion speed in a Zn-Al thermal metal spraying method was 0.66 time faster than that of the zinc galvanizing method in the estimation based on the standard of corrosion resistance service years in a zinc galvanizing method (JIS H 8641).
